Background: The relationship between dementia and time perception impairment is unknown.
Aim: This study aims to explore subjective perception of the passage of time in patients with Alzheimer’s disease (AD).
Methods: We conducted semi-structured interviews with 11 AD patients. Grounded theory, a qualitative research methodology, was used for data analysis.
Results: Based on interview transcripts, five categories were designated: {Live according to a private clock}, {The past comes up}, {Move back and forth between the present and the past}, {Cannot imagine the future}, and {Bid farewell to this world as early as tomorrow}.
Discussion: Our results suggest that AD patients alternate past and present without complete awareness and cannot imagine a future other than one ending in death.

Keywords: dementia, grounded theory, neuropsychology, qualitative study, mind time, interview
